IMPROVEMENT IN HINGES FOR SAFE-DOORS, &c'.'

i Specification forming part ofLetters Patent No. 154,995, dated September 15. 1874; application filed Ferbuary 13, 1874.

To all whom it may concern Beit known that I, HIRAM B. TRIPP, of South Boston, Suffolk county, State of Massachusetts, have invented an Improved Hinge, of Which the following is a specication:

This invention relates to a hinge for the hanging of safe-doors, more particularly those constructed with a square tongue and groove between jamb and door, and its object is to adapt a hinge to permit a door to be set in a direct line, out of or into its jamb.

The improvements are fully hereinafter de-A scribed.

In the accompanying plate of drawings, Figure l is a front View of a safe having its door hung by hinges of my improved construction, one hinge being shown in partial vertical section. Figs. 2 and 3, both horizontal sections, similarin every respect, except that in Fig. 2 the door is shown as set into its jamb, and in Fig. 3 as`set out of its jamb 5 Fig. 4, a detail view.

In the drawings, A represents a safe-door, B the frame, and C the jamb, of a square tongue-and-groove construction. These several parts are constructed as ordinarily, and

therefore need no more particular description herein. D, a hinge. The hinge D is constructed of two leaves E and F, arranged to turn upon or about a common pin or pintle, a, and the leaf E is secured to the door A, and the leaf F to the door-frame B. The pintle a, intermediately `of its length, has an eccentric collar, b, and the portion o of its length receives the one leaf, E, and the portion p of its length receives the vother leaf, F. The portion p includes the eccentric collar j). The leaf E is bored out, as at h, so as to receive the pintle portion o, as above stated, and the leaf F is also bored out, as at 11, so as to receive the pintle portion p and the eccentric collar b on such portion. The bore of the leaf E is cylindrical and of the same diameter as the pintle portion -o, and it extends along a portion ofthe width of the leaf. The

bore of the leaf F at r is oblong in a direction at right angles to the face of the leaf, and this oblong in width equals the diameter of the pintle portion p, and receives all of such portion except the eccentric collar b. For receivingthe eccentric collar b of the pintle a, the hinge-leaf Fis provided with a way, f, of a width equal to the diameter of the collar b, and this way f has walls g g, parallel to each other and at right angles to the side walls of the oblong portion r of the bore i to the leaf F. l, a screw-nut. rlhis screw-nut l is applied to the pintle a, and Secures it to the hinge-leaf F, as shown. v

In the drawings, two hinges, D, are Shown as applied to the door A and the door-frame,

and in their application the leaf E on the door is above the leaf F on the door-frame.

These two hinges B arel connected together through a common rod, G, which rod is the operating-rod in the application of the hinges shown in the drawings. The connection of the operating-rod G with the hinges D is made by the arms m of the rod, and the square portions n of the hinge-pintles a. Swinging the operating-rod G turns the two pintles a, a,

and in this turning of the pintles a e, by

the action of their eccentric collar b on the walls g in hinge-leaves F, the pintles are moved along the oblong bore r of the hingelleaves F toward the one or the other end thereof, as the case may be, and thus the hinge-leaves E are carried in a direction at right angles to and across the axis of revolution of the hinges upon or about their pintlesa.

Under the illustrated application of hinges D and operating-rod G to a safe-door and doorframe, shown in the drawings with the door in its jamb, as in Fig. 2, obviously before the door can be swung on its hinges it must be set out from its jamb. This is donefby pulling the operating-rod G outwardly from the safe-door, and this causesthe pintles a and hinge-leaves E to travel to the outer end of the oblong bore r in the hinge-leaves F, carrying, thereby, the door in a' direct line out of its jamb. If the voperating-rod G be swung toward the door, the door will be carried back into its jamb, the pintles a, in this instance, then moving to the inner ends of the oblong bore.

Although the improved hinge has been described in connection with a safe having a lsquare portions n, and the arms m, and verdoor and jamb constructed with a square tical rodGr, connecting the hinges together, tongue and groove it is not intended to limit and all operating as herein shown and dethe application of the hinge thereto. scribed.

Having thus described my invention What J I claim, and desire to secure by Letters Pat- H' B' TRU P ent, is- Witnesses:

In combination7 with the leaves E F, the ALBERT H. BROWN,

pintles a, having eccentric collars b, and W. O. SHAW.
